Abstract
BACKGROUND: Postoperative sore throat (POST) is a common complication following thyroid surgery with an endotracheal tube (ET). The I-gel® is a supraglottic airway device that has greater advantages in airway management compared with ET. This prospective trial aimed to explore the potential benefits of I-gel® compared with ET on POST. METHODS: In this trial, 106 patients, classified using the American Society of Anesthesiologists (ASA) physical status classification system, belonging to classes I and II, aged 18-65 years old who were prearranged for elective radical thyroidectomy, were randomly divided into the ET and I-gel® groups. All patients underwent total intravenous anesthesia (propofol, sufentanil, and cisatracurium). The incidence and severity of POST and postoperative hoarseness (PH) at 1, 6, 24, and 48 h following the operation were assessed and compared between the two groups. Moreover, the hemodynamic data during anesthesia were recorded and compared. Opioid consumption (sufentanil, propofol, and remifentanil) and postoperative nausea and vomiting were recorded. The visual analog scale scores for pain at the incision site 1, 6, 24, and 48 h postoperatively and Ramsay Sedation Scale scores were also evaluated and recorded. RESULTS: No significant difference was observed in the incidence of POST 1, 6, 24, and 48 h postoperatively (61.2% vs. 51.0%, P=0.309; 75.5% vs. 83.7%, P=0.316; 83.7% vs. 85.7%, P=0.779; and 12.2% vs. 22.4%, P=0.182, respectively) and the severity of sore throat (P=0.392) following surgery between the ET and I-gel® groups. The incidence of PH in the I-gel® group was significantly lower than that in the ET group 1, 6, 24, and 48 h postoperatively (all P<0.05). Compared with the ET group, a significantly less fluctuation in heart rate 1 min after intubation (P=0.045) and extubation (P=0.001) was observed in the I-gel® group. CONCLUSIONS: Although the I-gel® cannot reduce the incidence and severity of POST in patients with normal BMIs following thyroid surgery, it can reduce the occurrence and severity of PH compared with ET. The I-gel® showed superior results in terms of insertion time and better hemodynamic condition during intubation. AJTR
